This video will cover how to get into space research (such as astrophysics or astronomy) and some research that is going on.
For those looking into space related majors, your best options are astronomy and astrophysics. However, as an undergrad you will usually just start as a physics major then pick a more specific discipline in grad school.
You also will need to get a PhD if you want to do work in astrophysics or astronomy. There really aren't jobs in these fields for those with just bachelor's degrees.
Although the field is very competitive, if you have a true interest for the subject, most people will tell you to pursue it. Even if you don't land a job that you want, astrophysicists and astronomers can find work in other fields such as finance, engineering, software development, teaching, and more.

///
Stonehenge is a popular destination for summer solstice celebrations because the 5,000-year-old monument points toward the summer solstice sunrise on the horizon. However, it also points to the winter solstice sunset in the opposite direction and there's good reason to believe that this may have been the more important alignment for the Neolithic people who built Stonehenge. We investigate by constructing a tiny model of the Stonehenge monument.

However, any movement of a positive charge into a region of higher voltage requires external work to be done against the field of the electric force, work equal to that electric field would do in moving that positive charge the same distance in the opposite direction. Similarly, it requires positive external work to transfer a negatively charged particle from a region of higher voltage to a region of lower voltage.

The electric force is a conservative force: work done by a static electric field is independent of the path taken by the charge. There is no change in the voltage (electric potential) around any closed path; when returning to the starting point in a closed path, the net of the external work done is zero. The same holds for electric fields.

Work of art

A work of art, artwork, art piece, piece of art or art object is an aestheticphysical item or artistic creation. Apart from "work of art", which may be used of any work regarded as art in its widest sense, including works from literature and music, these terms apply principally to tangible, portable forms of visual art:

Work (Jimmy Eat World song)

"Work" is a song by Jimmy Eat World from their 2004 album, Futures. It was the second single released from that album. The song was written by Jim Adkins and features backing vocals by Liz Phair.

"Work" received positive reviews from critics, and it appeared on the Billboard Alternative Songs chart and the UK Singles Chart. A music video was released for the song; it featured interviews with high school students. Since the song's release, Jimmy Eat World have included it in their live performances.

Background

"Work" was written by Jimmy Eat World's frontman, Jim Adkins. According to Adkins, "'Work' is about doing something you know you shouldn't be doing ... It's about walking into an unhealthy situation, on purpose. Which could mean it's about an interoffice romance."

Liz Phair agreed to sing backing vocals on the song after the band played it for her. Adkins later said, "We're all fans of [Phair's album Exile in Guyville], so maybe a bit of a crush thing was happening. She definitely brings the sexiness. An unquantifiable sexiness, sure, but she definitely brings it. She was super cool to work with. 'Work' sounded like something she would sing, so we hunted her down through people we knew in Los Angeles. We showed her the song, she really liked it, so she came down and sang on it."

Crash Course

Plot

Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.

The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.

Crash Course (YouTube)

Crash Course (sometimes stylized as CrashCourse) is an educational YouTube channel started by the Green brothers, Hank Green and John Green, who are notable for their VlogBrothers channel. Originally, John and Hank presented humanities and science courses to viewers, respectively, although the series has since expanded to incorporate courses by additional hosts.

Crash Course was one of the 100 initial channels of YouTube's $100 million original channel initiative. Crash Course launched a preview on December 2, 2011. As of February 14, 2016, the Crash Course YouTube channel has gotten 3,947,842 subscribers and has received over 300 million video views. In November 2014, Hank Green announced that a partnership with PBS Digital Studios would allow them to produce more courses, starting in January 2015.

Currently there are fourteen seasons of Crash Course, with Hank and John each hosting five. Together with Emily Graslie, they co-hosted Big History. As part of the PBS partnership, Phil Plait and Craig Benzine have hosted series about Astronomy and U.S. Government and Politics, respectively. A second channel, Crash Course Kids, is hosted by Sabrina Cruz and has started its first series, Science.

Crash Course (game show)

Crash Course is an American game show that premiered on ABC on August 26, 2009. It is hosted by Orlando Jones and Dan Cortese. The series has teams of two competing for a golden steering
wheel and $50,000. The series was aimed to try and outbest Wipeout, but failed to beat its audience and has been canceled after three aired episodes (but four were produced).

Premise

Hosted by Orlando Jones and Dan Cortese. Five teams of two are revealed at the beginning (Siblings, Mother-Son, Best Friends, Single Moms, Roommates, Neighbors etc.). The first round has all five teams competing, for example, in car bowling, the team with the lowest amount of pins would be eliminated.

For round two, the four teams would tackle an even more difficult challenge, another example, in Catch Me If You Can, the teams would fight through barrels to get up on a platform. Some cars don't make it and fall upside-down sometimes. The team who doesn't make it up as far or with the slowest time is eliminated.

Distances: Crash Course Astronomy #25

How do astronomers make sense out of the vastness of space? How do they study things so far away? TodayPhil talks about distances, going back to early astronomy. Ancient Greeks were able to find the size of the Earth, and from that the distance to and the sizes of the Moon and Sun. Once the Earth/Sun distance was found, parallax was used to find the distance to nearby stars, and that was bootstrapped using brightness to determine the distances to much farther stars.

Binary and Multiple Stars: Crash Course Astronomy #34

Double stars are stars that appear to be near each other in the sky, but if they’re gravitationally bound together we call them binary stars. Many stars are actually part of binary or multiple systems. If they are close enough together they can actually touch other, merging into one peanut-shaped star. In some close binaries matter can flow from one star to the other, changing the way it ages. If one star is a white dwarf, this can cause periodic explosions, and possibly even lead to blowing up the entire star.

Stonehenge is a popular destination for summer solstice celebrations because the 5,000-year-old monument points toward the summer solstice sunrise on the horizon. However, it also points to the winter solstice sunset in the opposite direction and there's good reason to believe that this may have been the more important alignment for the Neolithic people who built Stonehenge. We investigate by constructing a tiny model of the Stonehenge monument.

The astrolabe dates to ancient greece and was used to perform a number of transformations between time and observations of stars and the sun. While modern technology has rendered them redundant they are still nice to play with as a tactile analogue computer that can be displayed as a scientific work of art.

What You Should Know About Getting a Career In Astronomy/Astrophysics

This video will cover how to get into space research (such as astrophysics or astronomy) and some research that is going on.
For those looking into space related majors, your best options are astronomy and astrophysics. However, as an undergrad you will usually just start as a physics major then pick a more specific discipline in grad school.
You also will need to get a PhD if you want to do work in astrophysics or astronomy. There really aren't jobs in these fields for those with just bachelor's degrees.
Although the field is very competitive, if you have a true interest for the subject, most people will tell you to pursue it. Even if you don't land a job that you want, astrophysicists and astronomers can find work in other fields such as finance, engineering, software development, teaching, and more.

However, any movement of a positive charge into a region of higher voltage requires external work to be done against the field of the electric force, work equal to that electric field would do in moving that positive charge the same distance in the opposite direction. Similarly, it requires positive external work to transfer a negatively charged particle from a region of higher voltage to a region of lower voltage.

The electric force is a conservative force: work done by a static electric field is independent of the path taken by the charge. There is no change in the voltage (electric potential) around any closed path; when returning to the starting point in a closed path, the net of the external work done is zero. The same holds for electric fields.
